How to Change Radiobutton Icon against theme set in Windows Phone 8 - xaml

In my application I am using not using windows default theme color for background instead of this I have used White color is my default. Now I am changing the content colors of the controls. Now all others are working good but in RadioButton I am getting some issue to set the RadioButton Icon color as it is still showing white according to phone theme(Phone theme is Black)
Do I need to set any external style for that? Can anyone please guide how I will achieve this?
Here is my code:
<ListBox Name="lstPollsQuestion" Grid.Row="1">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<RadioButton Name="rdbBlockTitle"
Margin="0,0,0,-20"
Height="72"
GroupName="PollQuestion"
Click="RadioButton_Click"
FontFamily="Segoe WP Light"
Tag="{Binding Path=questionId}">
<RadioButton.Content>
<TextBlock Text="{Binding Path=question}" Foreground="Black"/>
</RadioButton.Content>
</RadioButton>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
screenshot of the page

If we take a look at the default template for the RadioButton towards the bottom there's an Ellipse named "CheckGlyph" with Fill="{ThemeResource RadioButtonForegroundThemeBrush}" declared. So you can change it on the template level or that particular resource color.

Change the default ToggleButton with MaterialDesignInXaml

I have some big prominent color-coded ToggleButtons in my WPF app. I am trying out MaterialDesignInXAML, however the toggle buttons default to very small switches. How can I use a larger toggle button?
You can see how the default looks here:
I'm using TextBlocks as button labels to accommodate word wrapping.
Each ToggleButton is like this:
<ToggleButton Width="200" Height="200" Grid.Row="0" Grid.Column="0" Margin="10"
Name="Game0"
Foreground="{Binding Game0TextColor}"
Background="{Binding Game0Color}">
<!--Use TextBlock for word wrapping button text-->
<TextBlock TextWrapping="Wrap"
VerticalAlignment="Center"
TextAlignment="Center"
FontSize="22"
Foreground="{Binding Game0TextColor}"
Text="{Binding Game0Title}" />
</ToggleButton>
Assuming you have pulled in the prescribed boilerplate, you can override a default style in a particular view as follows:
<Window.Resources>
<ResourceDictionary>
<!--
Override style for ToggleButton to use because default is a small switch
Try also MaterialDesignFlatPrimaryToggleButton
-->
<Style TargetType="ToggleButton"
BasedOn="{StaticResource MaterialDesignActionToggleButton}" />
</ResourceDictionary>
</Window.Resources>
See Toggle Button examples on the wiki page and in the demo app.
Also have a look at the guide for Overriding-Default-Styles if you want to change styles app-wide or factor it out.

UWP PersonPicture control background not being set

PersonPicture is a control offered in Microsoft's Universal Windows Platform.
It looks great, which is why I'm trying to use it to display a user's initials with a background color.
The problem is that when I set the control's background to a color, the background is not changed on the display.
<PersonPicture Initials="JF"
Background="Red"/>
In the above code, the Background still remains the default, while everything else is updated.
Please if you have been able to set the background color, share how you've done it!
I found the template for the PersonPicture through this question: How to get all Controls' ControlTemplates Programmatically?(UWP)
The PersonPicture ignores its Background property and uses a couple of brushes that make up the colors of the control depending on Dark/Light theme and some hard coded values.
It draws an ellipse/circle and thus shows its container's color in the four corners.
Assuming you want to set the color in the square that contains the picture you could do this:
<Grid Background="Green">
<Grid HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="Red">
<PersonPicture />
</Grid>
</Grid>
The first grid represents a page. The second grid tightly wraps around the PersonPicture:
Note how the personpicture is somewhat transparent and shows the color of the grid. The color that the template uses for the ellipse is #77FFFFFF
So you could take it a step further by adding an ellipse:
<Grid Background="Green">
<Grid HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="Red">
<Ellipse Fill="White"/>
<PersonPicture />
</Grid>
</Grid>
This allows you to control the color of the picture somewhat by setting the color of the ellipse:
Do note that it still mixes the PersonPicture with the background so you cannot set it to black:
<Grid Background="Green">
<Grid HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="Red">
<Ellipse Fill="Black" />
<PersonPicture />
</Grid>
</Grid>
Shows:
And finally, you could copy the template (see: How to get all Controls' ControlTemplates Programmatically?(UWP))
and adjust it to use the Background property.

How to change listpicker dropdown ItemTemplate background?

I have a Windows Phone 8 listpicker that I'm trying to change the background color of, however, it only seems to change the item background and not the dropdown box background as you can see in the screen capture. The dropdown box seems to be binded to the WP8 theme. How can I change the background of the entire dropdown box and not just each individual item?
<toolkit:ListPicker x:Name="BackgroundListPicker" Background="Black" ItemsSource="{Binding BackgroundsList}">
<toolkit:ListPicker.ItemTemplate >
<DataTemplate x:Name="BackgroundItemTemplate" >
<Grid HorizontalAlignment="Stretch" Background="Black" VerticalAlignment="Stretch" Margin="0,0,0,0">
<StackPanel Orientation="Horizontal">
<Image Source="{Binding BackgroundThumb}" Width="30" Height="30" HorizontalAlignment="Left" />
<TextBlock Text="{Binding BackgroundName}" Foreground="White" Margin="12,0,0,0" HorizontalAlignment="Right"/>
</StackPanel>
</Grid>
</DataTemplate>
</toolkit:ListPicker.ItemTemplate>
</toolkit:ListPicker>
So your issue was that you were attempting to apply an image to an item. When you needed to hit the control itself that the items populate via ItemsPresenter so by pulling out the default style template for the control, and either making a place to pass in your image for an instance, or placing one directly into the template itself. You get your resulting background image for the ListPicker background to fall behind the items populating it.
Glad you found your remedy! Cheers.

Screen does not display full content of string

i'm using the textblock to display the content,but for the long content, it just cut off and not display the content fully while i'm sure that the i filled the content string. Pls show me where my code is wrong. Thanks
Link of the my screen: www.flickr.com/photos/37903269#N05/15332152972/
my xaml code :
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<!-- <phone:WebBrowser VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Name="webBrowser1" /> -->
<ListBox Name="Listbox_DetailPage">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Content}"
TextWrapping="Wrap"
Style="{StaticResource PhoneTextNormalStyle}"
HorizontalAlignment="Center"
/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Grid>
I executed the code shared and it seems to wrap text as shown in the screen shot below.
The screenshot you shared seems to have vertical cropping of the text as well. For that, we can set the ScrollViewer.VerticalScrollBarVisibility to 'Auto' with proper Height given.
Also, for your additional knowledge or may be future use, here are some stackoverflow questions which explains the text 'NOT WRAPPING' issue for StackPanel
TextBlock TextWrapping not wrapping inside StackPanel
TextBlock TextWrapping not wrapping
actually, i fixed it.Because of the limitation of sing UI: 4096px limit of size. So there is a need to split the long content in the more than one TextBlock or you can create a scrollabe textbock as here

Get Popup new target origin when screen edge is encountered

I have an issue with popup placement and especially the target origin.
I want to apply a Metro UI style to my combobox so there's no border between the textbox and the itemslist.
It works well when the popup is placed at the bottom
Placement="Bottom"
but when it encounters the bottom edge of the screen the target origin becomes the top of the placement target.
I'd like to know when the target origin changes to the top left corner, that way i could change the borderthickness of the control. Unfortunately the placement property is not reset to the new target origin so I'm a bit lost here.
Here's the code of the usercontrol.
The placement is set to custom here, it's the only workaround i've found to have something that suits me. But if I want metro like comboboxes I need to know where the popup really shows up...
<Grid>
<formElement:LabelBoxPC x:Name="NameFilter"
LabelName="{Binding FilterLabel,
ElementName=UCInlineFilterPreSelected}"
TextBoxCommand="{Binding GoToEntityManagementCommand}"
TextBoxValue="{Binding SearchValue,
Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}">
<formElement:LabelBoxPC.InputBindings>
<KeyBinding Key="F4" Command="{Binding GoToEntityManagementCommand}" />
</formElement:LabelBoxPC.InputBindings>
</formElement:LabelBoxPC>
<Popup x:Name="ResultsGrid"
Placement="Custom"
IsOpen="{Binding ElementName=NameFilter, Path=TextBoxFocus, Mode=OneWay}"
AllowsTransparency="True"
Focusable="False"
PopupAnimation="None">
<StackPanel>
<Border Padding="5px" Background="#FFF" BorderBrush="#000000" BorderThickness="2,2,2,0">
<Button HorizontalAlignment="Right" Style="{StaticResource SmallIconButton}" Background="{StaticResource DarkCloseIcon}"></Button>
</Border>
<ListBox x:Name="Results"
Width="220"
Style="{StaticResource InlineFilterListBox}"
Height="150"
ItemsSource="{Binding Results}"
SelectedItem="{Binding SelectedObject, ElementName=UCInlineFilterPreSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</StackPanel>
</Popup>
</Grid>
